Hi Andrew,
you may want to implement a lookup table populated with the stopwords and only stem a word in input if it is not in the stopwords table.
It should be quite easy to implement in Java, but let me know if you need assistance.
Have a nice day,
Oerd

Hi Olly
I imagine removing stop words is a fairly common requirement. Any idea how people implement stop word removal with snowball?
The reason I originally thought snowball provided stop word removal was because of the following links http://snowball.tartarus.org/algorithms/english/stop.txt (from http://snowball.tartarus.org/algorithms/english/stemmer.html)
It seems to suggest there is some stop word support
Thanks
Andy

today I downloaded the java version of snowball and compiled it. I ran
a couple of little example through it. It does not appear to remove
stop works. Is this a bug?
That's not a bug - snowball is a stemmer, not a stopword remover.
Cheers,
Olly
